IViINE-CAGE.

Application filed January 2 1 '0 alt whom it may concern: I

Be it known that 1, PAUL 1V. llons'rnin, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Mine- Cages, of whichthe following is a specification, reference being had therein to theaccompanying drawing.

This invention relates to mine cages, and has for its special object toprovide mechanism whereby a car can be run uponthe cage at a landing,and held more securely in position than hitherto while the cage is beinglifted to the surface of the ground and there emptied of its contents.

Other minor objects will be apparent from a reading of the followingspecification in connection with the drawings, of which- 7 Figure 1 is across sectional side elevation of the mine cage in position the bottomof its shaft, andadjacent parts of the mine, F 2 is a similar crosssectional view at an intermediate landing likewise showing adjacentparts of the mine, the upper part of the cage being broken away. Fig. 3is a view in side elevation of the cage at the upper limit of its traveland of the mechanism for dumping the mine car, the tilting platformbeing shown in position to discharge the contents of the car. Fig. i isa plan view of the car, one half being shown in section, with horiZontal cross section of the shaft. ll 5 is anend elevation of the minecage. Fig. 6 is a perspective view of the safety catch mechanism.

The cage comprises essentially two parts, the sling frame A and thetilting platform H, pivctally secured to each other at their lower ends.The sling frame can be most satisfactorily constructed of structuralsteel, as shown in the drawings, consisting of the vertical sidechannels A joined by theupper horizontal channels A and the lowerhorizontal channel A. To the outside faces of the channels A? aresecured guide blocks B which engage with the slides C which may be woodor metal strips, to hold the cage in place laterally, while permittingfreedom of motion vertically. lliveted to the top side of the upperflange of the channels A- is the yoke D through which the draw-bar l)passes. Biveted to the under side of the lower flanges of the channelsA} mid Specification of Letters Patent.

way between the ends of the channels is the plate A Through a'hole inthe center of this plate the draw-bar D is guided in its verticalmotion. By means of the spring D surrounding the draw-bar and placedbetween the under side of the yoke 13- and the nut upon the drawbar, ayielding suspension is provided so that the car will be lifted withoutshock, and a jerky motion in the hoisting mechanism will be to a largeextent absorbed.

The cage is provided with the safety device indicated as a whole by E.Mounted in brackets E carried by the channels A is theshatft E keyed towhich are the toothed cams E A chain ll attached to the under side ofthe segmental sheaves E at one end, and at the other to the clamp 19]secured to the draw-bar D holds the toothed cams out of engagement withthe slide wheneyer there is tension in the hoisting rope. When for anycause this tension is released, the spring E throws the cams intoengagement with the-slide and any small descent of the car causes themto sink deeper into the slide, as they revolve about the shaft E untilthe cam surface impinges on the upper face of the inner surface of thehousing E which is preferably cast integral with the bearing brackets EThe traction block E integral with the plate E of the bracket casting,forms with the brackets a shoe which on gages with the slide andprevents the lateral. displacement of the cage, as a whole, under theside thrust of the revolving cam E The housing, E assists the shaftbearing proper in preventing the cams from turning clear over, when theyare thrown into ac tion. Tightening the hoist rope will innne diatelythrow these cams out of engagement leaving the cage free to slide up ordown.

A canopy is provided to protect workmen in the cage from falling bodiesand consists of the two'plates F F which are hinged to the plate F thelatter being secured to the top of the upper flanges of the channels ATo the under sides of the plates FF are riveted the plates F the inneredgesof which abut against the central parts of the slin frame thusservin to hold the two sides of the canopy in horizontal position, whileat the same time strengthening the canopy structure, as a whole. Byhinging the canopy in this manner either of the sides can be swung intoa Vertical position to per? frame. The upper ends of which are joinedmit of the lowering down the shaft of rails, long pieces of timber,etc.

The bearing supporting plates G for the tilting frame are riveted to theinner faces of the lower ends of the channels A and carry the bearingblocks G in which is mounted shaft G. JPivoted upon this shaft are thevertical channels H of the tilting by the shaft H rotatably mountedtherein. In this mannerthe tilting frame is secured at the bottom and alittle to one side of the sling frame. Its center of gravity, as awhole, being normally in the vertical plane of'the channelsA so that theshaft H rests by the'action of gravity against the brackets H secured.to the upper end of the sling frame.

e The shaft H carries a pair of rollers H which engage with guides Hlocated at the top of the shaft-to give the platform a forward movementwhen the sling frame is a raised vertically sothat the contents of thecar carried'by the platform may be discharged. The guides are curved, asshown in the drawings, in such a Way that this dumping movement isgradual and takes place Without shock tothe car. The vertical,

boards H ,-v\'l1ich form a continuation of the upper ends of theguiderails H cause the car to be maintained at the same tipping angle,6;, about 45,if the sling'frame is raised above the tipping plate. I

Riveted to the channels H neartheir lower ends are the channel beams Hwhich are braced thereto by the plates H and the diagonal struts H Themule guard plates H 9 are secured to the channels H and the struts H Thechannel beams H with the end channels H and the central l-beam H form ahorizontal framework upon which the car-supporting tracks 1 and floorboards J are supported. The latter are suitably secured to the endchannels H upon which they rest. The tracks I are made in two sections,as shown,each section being hinged at its outer end to the end channelsH by means of the bearing brackets M secured thereto, the shafts Imounted therein and the plates M hinged to the shaft, and riveted to therails. The two rails of each section of the track are connected togetherby the channels N riveted to the. under side of the rail-flanges andbraced by the plates N Also riveted to the under side of therail-flanges are the bumpers I which rest upon the upper face of theI-beams I hinged at one end to the shaft 0 mounted in the bracketssecured to the inner faces of the end channels H". Three other tie-rodsO serve to connect and hold in rigid relation to each other the channelbeams along the remainder of their length. These channel beams are thusfree to swing upon a horlzontal axis through the small angle ll111 itedinan' upward direction by the channels H and I-beams H and in adownwardydirection by the stirrup i suspended from the central I-beam I-When therefore the mine cage is at the bottom of the shaft, as

ing upward if these levers K have been inadvertently-left in operativeposition, they will automaticall be thrown out-of the path of travel ofthe cage. On the other hand, if the cage is descending and if by thelever K the levers K have been thrown into operative position thechannels'l will be swung upward relatively to the channels I and incontact therewith, so as to elevate the tracks to a horizontal position.

When the mine car Q has been moved on to the cage and the cage beginsits ascent,

the track sections swing about their pivotal Y supports until theirinner ends rest upon the lower flange H of the central I-beam H? and thecar, as a whole, is lowered relatively to the cage until the axles Q orany other suitable projection of the car settles into the notches 1formed in the skids 1 until the body of the car rests upon the skids.These skids aresecured to the platform boards J. By this simpleexpedient the car is securely maintained in position upon the tiltingplatform, while the latter is being moved up and down the mine shaft andwhen it is being tipped at the surface of the mine without putting anystrain upon the car wheels, or running gear.

in order to stop the car upon the tilting platform exactly that pointwhere the car axles will be directly above the notches T the latch 11notched to receive the downwardly projecting part of the L-shaped lug Lattached to the bottom 'ofthe car, is pivotally mounted in the latchcarrying block L This block is free to slide longitudinally in suitableg ideways formed in the base block L, which is secured to the platformboards. The block L is held in position at one end of its'range ofmovement by the spring L" which takes the shock of the sudden contact ofthe lug L of the moving car with the latch L. The latch L is normallyheld in engagement with the l g by the spring L acting throu h the rod Llever L and the arm L keyed to the shaft L on which the latch is rigidlymounted. At the lower landing the tagger R is installed consisting ofthe arinlt keyed to the rock shaft'lt to which is also wheel keyed thearm It"; This arm contacts with the end of the rod R, which is suitablymounted on the mine floor, and is provided with the bumper R adjacent toand in line with the bumper L on the end of the rod If. A spring Itholds the bumper B normally away from the bumper L An oncoming mine carautomatically operates the tugger It, and through the rod If and leverIf, releases the latch L, leaving the car on the cage free to move offwhich it does when the oncoi'ning car strikes itsbumpers. The oncon'iingcar is then caught by the latch and held in position on the cage.
